How do I attach anything to PS_GPIO in xillydemo? It says multiple drivers but what if I want to write HDL code to read in a switch and set an LED? Both are defined as PS_GPIO (1 through 7 and 11-18 I think) but if I try to set them I get the conflict becuase they are already used in the xillybus_ins module on line 250ish. Essentially I just want to know what to do to set a light when I flip a switch with Xillybus. As it is I can't use any of the ports. I have tried everything I can think of, including a seperate module that I parameterize in the bottom of xillydemo and feed in the PS_GPIOs as lines. That approach gives no errors, but it acts as if the module isn't even there. Thanks a ton in advance for any help!
